官网介绍
$request_time – Full request time, starting when NGINX reads the first byte from the client and ending when NGINX sends the last byte of the response body
$upstream_connect_time – Time spent establishing a connection with an upstream server
$upstream_header_time – Time between establishing a connection to an upstream server and receiving the first byte of the response header
$upstream_response_time – Time between establishing a connection to an upstream server and receiving the last byte of the response body

$upstream_connect_time 是建立连接的时间
$upstream_header_time 从建立连接到发送第一个响应头字节的时间
$request_times 是从请求到建立连接到发送完最后一个内容字节的时间
$upstream_response_time 是从建立连接到发送完最后一个内容字节的时间,这个是我们需要关注的,因为客户端的请求和客户所在网络有关

使用下面这个日志格式,看的参数比较全

log_format apm '[$time_local]\tclient=$remote_addr\t'
'request="$request"\t request_length=$request_length\t'
'http_referer="$http_referer"\t'
'bytes_sent=$bytes_sent\t'
'body_bytes_sent=$body_bytes_sent\t'
'user_agent="$http_user_agent"\t'
'upstream_addr=$upstream_addr\t'
'upstream_status=$upstream_status\t'
'cookie="$http_cookie"\t'
'request_body="$request_body"\t'
'document_root="$document_root"\t'
'fastcgi_script_name="$fastcgi_script_name"\t'
'request_filename="$request_filename"\t'
'request_time=$request_time\t'
'upstream_response_time=$upstream_response_time\t'
'upstream_connect_time=$upstream_connect_time\t'
'upstream_header_time=$upstream_header_time\t';
